Abstract: The sex pheromone components of Spodoptera litura from China were identified by using analytical technique of single female sex pheromone gland. The individual differences, daily changes and scotophase rhythms of these components were studied. Electroantennogram (EAG) responses of male to these components and its mixture were recorded. Four components, Z9, E11-14∶Ac(A),Z9, E12-14∶Ac(B),Z9-14∶Ac© and E11-14∶Ac(D), were found in the female sex pheromone gland at a ratio of 100∶27∶20∶27.

Key words: Spodoptera litura, sex pheromone, communication system, EAG bioassay
